Confused whether to buy Logitech g400s or not ?

[xrock8]

My hands are quite big(20 cm long and 11cm wide) and today i bought a cm storm xornet mouse and it felt quite small and uncomfortable ...!
I previously had a Razer Krait which was pefect for my hands .. !!
I am now thinking of getting a g400s and wanna know if it will be suitable for my hands ???
